Thanks for responding Mark,
To clarify I can change the logging level of the route to any level below and
to the initial INFO level - I can change between ERROR, WARN and INFO and see
the requisite changes in the apps logging. This issue seems to arise whenever I
want to raise it above INFO, for example updating the logs to DEBUG level, no
DEBUG log lines are logged. This makes me think that there is a logger higher
up in the hierarchy than the routes logger itself blocking it.
For clarity my package structure looks like this
- src
- main
- java
- my.package
- controllers
TestLoggersController.java
- routes
TestLoggersRoute.java
MyApplication.java
Kind Regards
Simon

It looks like your route Builder classes in the root package. That usually
is not good as if that's the case. I suggest moving it to the same package
as the controller. I don't know if that will make any difference but
sometimes having classes in the root package causes issues. Other than that
I can't see why things are not working. Other than Maybe because routes are
created initially on Startup it's not sensing the logging level change
which is weird. I'll have to confirm that tomorrow. Which is door today I
think.
